Prof Eun-Jung Holden is a co-leader of the geophysics and image analysis theme within CET. She gained a PhD in computer science at UWA specialising in computer vision and visualisation algorithms. She made a transition to geoscience in 2006 and since then she established and now leads The Geodata Algorithms Team within CET. The Geodata Algorithms Team consists of researchers who were trained in computer science, engineering and applied mathematics. Equipped with a strong capability in computational algorithm design and implementation, the team has built expertise in understanding the nature of geodata and their use in industry workflows by collaborating with geoscientists in academia and industry. The uniqueness of this team is in the ability to span the boundaries of computational science and geoscience and the boundaries of academia and industry. The team won various awards for student projects and research including The UWA Vice Chancellor’s Research Award in Impact and Innovation for 2015.

Prof Holden is currently working closely with mining companies in optimising their drill hole data integration and interpretation using data mining techniques; and with The Geological Survey of Western Australia through an Australian Research Council Linkage (LP140100267) in developing a GIS-based new visual analytics platform called Integrated Exploration Platform (IEP) to support the mineral explorers operating in Western Australia in improve their geological interpretation of exploration data. Prof Holden is committed to deliver new data analytics methodologies as practical tools to the industry, which led to the commercialisation of three software products which are used by the minerals and petroleum industries and consultancies globally.

Research Output Dissemination

Public Domain Software Product
​

Integrated Exploration Platform (launched as a GSWA product at the GSWA Open Day, 2016) – This GIS based platform was developed in collaboration with GSWA and provides state-of-the-art data analytics tools to support ‘interpreter driven and computer supported’ interpretation workflow.

Commercial Software Products
​

The CET Grid Analysis extension for Geosoft’s Oasis Montaj
(More than 90 licenses of this software were sold and it widely used by mining and petroleum companies as well as consultancies globally).

The CET Porphyry Detection extensions for Geosoft’s Oasis Montaj
(This software was developed in collaboration with Barrick Gold, the world’s largest gold producer in their global porphyry exploration programs. It has been credited with contributing to the discovery of the Luciano porphyry cluster in the Casale district, Chile).

Image & Structure Interpretation Workspace (automated structure picking and analysis methods) for ALT’s WellCAD (WellCAD is the most widely used televiewer image analysis software globally by petroleum and mining companies, and this workspace featuring our algorithms and workflow was released in 2015. The algorithms and workflow were developed mainly through a Rio Tinto sponsored project between 2010 and 2013).
